Hi, I'm Mark on behalf of Expert Village. In this next segment we are going to go over
the ingredients used in brewing. There are four main ingredients in brewing. There is
malt, hops, yeast, and water. Malt is usually going to come in two different forms. You
have your malt extracts; you can get a dry version which is a little more concentrated
than the liquid version but a little more expensive or you can get the liquid version
which is like a very, very thick syrup. The other forms of malts that you're going to
be adding to really kind of flesh out the character of the beer that you are making
are specialty grains. These are grains that have been roasted somewhat differently, maybe
steamed for a little while. And basically, they are going to add some of your more complex
flavors. When you get your specialty grains, your home brewing store will help you mill
them like this.
This will open up the grain allowing extraction of the sugar and the color. Next, we have
hops. And there's two major forms of hops that are available. There's whole hops, which
you can see right here. This is actually just the cone of a hop. And then there's also pellet
hops which is basically all of your whole hops crushed up and then put into a condensed
form. The differences between the two: whole hops tend to have a shorter shelf life where
as pellet hops will last longer. You will also get a slightly better extraction out
of pellet hops than you will out of whole hops. However, for todays purposes, in our
brewing session, we are going to be using whole hops because they are a little easier
to get out of the wort. Hops can add three things to your beer; first, they can add bitterness,
then they can also add flavor and finally, they can add aroma. Hops which are added early
in your boil around sixty minute-time frame will add primarily bitterness as the flavor
and aroma components are boiled off. Hops that are added in the twenty to ten minute
time frame will add flavor. They will also add a little bitterness, but mainly flavor.
And finally, the aroma hops which are added usually in the ten and under time frame down
to actually just steeping will add mainly just aroma characteristics.
